Flutter - 'initialValue == null || controller == null': is not true. error
You can't use both initialValue
and controller
at the same time. So, it's better to use controller
as you can set default text in its constructor.
Here is an example.
// Create the controller.
final controller = TextEditingController(text: "Your initial value");
Widget build(BuildContext context) {
return TextFormField(
controller: controller, // Assign it here.
// ...
);
}
To get the value entered by the user, use:
controller.text
